Group 1 - The concept of cultivated diamonds has gained significant momentum, with companies like Huifeng Diamond rising over 26%, Power Diamond over 19%, and others showing substantial gains [1] - A research team from Peking University has made a breakthrough in the preparation and application of diamond film materials, developing a method for mass production of large-sized, ultra-smooth, flexible diamond films [1] - The new method allows for the production of large-area (2-inch wafers), ultra-thin (sub-micron thickness), ultra-flat (surface roughness below nanometers), and ultra-flexible (capable of 360° bending) diamond films, which can be used in various applications including micro-nano processing and strain engineering [1] Group 2 - Diamonds are recognized as a "hexagonal warrior" and "ultimate semiconductor" due to their excellent thermal conductivity, carrier mobility, and breakdown field strength, making them a key material in semiconductor applications [2] - Major cultivated diamond companies in China, such as Power Diamond, are actively expanding their production capacity, with Power Diamond planning over 2 million carats in 2022 [2] - Domestic companies are making strides in "diamond heat dissipation" technology, applying CVD and HTHP techniques in semiconductor substrates, films, and heat sinks, with breakthroughs reported by companies like Power Diamond, World, and others [2] Group 3 - Diamond heat dissipation is seen as a next-generation cooling technology with significant industrial potential in the AI era, with China poised to leverage its complete industrial chain and export restrictions on upstream materials [3] - The development of diamond heat dissipation technology is in the "from 0 to 1" stage in China, indicating a promising trajectory comparable to international advancements [3]
